Removing redundant pressure sensor events

Removing redundant pressure sensor events

PRESSURE_BASE_DATA_SET and PRESSURE_EVENT_RAW_DATA_REPORT_ON_TIME were the same PRESSURE_BASE_DATA_SET has been removed.
PRESSURE_BASE_DATA_SET was used for polling events and PRESSURE_EVENT_RAW_DATA_REPORT_ON_TIME was used for event driven
Since both these represent the same pressure event, DATA_SET type has been removed.

And PRESSURE_EVENT_RAW_DATA_REPORT_ON_TIME has been renamed to PRESSURE_RAW_DATA_EVENT to make it simpler.

The change has been tested on rd-pq device for all sensord API and all API were found to be working.
